Description

Technical Field

[0001] The present invention relates to the technical field of obtaining and purifying domestic water in high-altitude cold regions, and in particular to an integrated ice-melting, water-supplying and water-purification station in high-altitude cold regions. Background Art

[0002] In high-altitude and frigid regions, water resources primarily come from snow and glacier meltwater, which flows into rivers and lakes to replenish freshwater. However, due to climatic conditions, meltwater dissolves a relatively large amount of surrounding salt during its flow, resulting in high total hardness in river water. Lake water, on the other hand, is mostly stagnant, rich in various salts through long-term sedimentation and evaporation, resulting in a moderately to strongly bitter and salty taste. Its pH reaches a maximum of 9.52, indicating a high alkalinity content. Due to differences in natural conditions and the historical stages of lake development, the total hardness of lake water varies significantly, ranging from a low of around 1000.0 mg / L to a high of over 100,000.0 mg / L. Therefore, when drawing water from rivers and lakes for domestic use in high-altitude and frigid regions, purification is essential for the health of personnel and the safety of engineering projects. During the purification process, due to the low temperature in the area, especially in the cold season when the local temperature drops to around -30℃, when there is residual water or water vapor in the water purifier rich in capillaries and its water supply pipes and water transmission pipes, it is very easy to freeze and crack, thereby damaging the water purifier or water purification equipment.

[0003] In order to solve the water shortage problem in high-altitude cold areas, it is necessary to study an ice-melting and water-dissolving device suitable for high-altitude cold areas, which integrates water supply and water purification. The ice and snow can be collected, heated and melted into water, and the melted water can be further purified to meet the requirements of domestic water use. Summary of the Invention

[0032] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, a high-altitude cold zone ice melting water supply and water purification integrated station includes a spray-type rapid ice melting water supply device 1, a hot water boiler 2, a vacuum multi-stage cascade water purification device 3 and a desalination water purification device 4. The water outlet of the spray-type rapid ice melting water supply device 1 is connected to the water inlet of the vacuum multi-stage cascade water purification device 3, the water outlet of the vacuum multi-stage cascade water purification device 3 is connected to the water inlet of the desalination water purification device 4, and the water outlet of the desalination water purification device 4 is connected to the external water pipeline; the spray-type rapid ice melting water supply device 1 is connected to the water inlet of the vacuum multi-stage cascade water purification device 3, and the water outlet of the vacuum multi-stage cascade water purification device 3 is connected to the water inlet of the desalination water purification device 4. The water outlet of the rapid ice-melting water supply device 1 is also connected to a meltwater straight-discharge pipe 5, and a straight-discharge quick connector 7 is provided at the end of the meltwater straight-discharge pipe 5; the water outlet of the vacuum multi-stage cascade water purification device 3 is also connected to a clean water straight-discharge pipe 6, which is communicated with the meltwater straight-discharge pipe 5, and a check valve is provided on the meltwater straight-discharge pipe 5 between the clean water straight-discharge pipe 6 and the spray-type rapid ice-melting water supply device 1; the spray-type rapid ice-melting water supply device 1 is also connected to a hot water boiler 2 for providing hot water for spraying ice melting.

[0034] The working principle is as follows: Ice and snow can be melted and water produced by the spray-type rapid ice-melting water supply device 1. If the meltwater quality meets the standards, most of the meltwater is directly discharged through the meltwater discharge pipe 5, and a small portion enters the hot water boiler 2 as a spray water source. If the meltwater quality does not meet the standards, most of the meltwater enters the vacuum multi-stage cascade water purification device 3 for purification, and a small portion continues to enter the hot water boiler 2 as spray water. After purification by the vacuum multi-stage cascade water purification device 3, if the water quality meets the standards, it can be directly discharged through the purified water discharge pipe 6 for use. If the water quality does not meet the standards, it can be sent to the desalination water purification device 4 for further capacitive desalination and purification. After purification, it can be used externally. In addition, the vacuum multi-stage cascade water purification device 3 and the desalination water purification device 4 are also equipped with a vacuum drainage system to drain residual water in the equipment or pipelines to prevent low-temperature freezing and damage.

[0035] The water quality is judged to meet the standards based on the "Outdoor Water Supply Design Standard" (GB 50013-2018), the "National Drinking Water Quality Standard" (GB 5749-2006) and the "National Drinking Water Standard Test Method General Rules" (GB / T 5750.1-2006).

[0036] The hot water boiler 2 can be any one of an electric hot water boiler, an oil-fired hot water boiler, a gas-fired hot water boiler and a coal-fired hot water boiler in the prior art, so as to provide spray hot water for the spray-type rapid ice-melting water supply device 1 .

[0037] The specific structure and working principle of each device of the integrated ice melting, water supply and water purification station of the present invention are given below.

[0038] 1. Spray type rapid ice melting water supply device

[0039] like Figure 2-4 As shown, the spray-type rapid ice-melting water supply device 1 includes a first skid-mounted base 101, on which a melting refrigerator 102 is installed. The melting refrigerator 102 is provided with an ice-dropping deceleration trough 118, an ice-melting residue trough 119, a cleaning spray pipe 122 and a residue guide plate 123 from top to bottom. The ice-dropping deceleration trough 118 and the residue guide plate 123 are both inclined. The lower end of the ice-dropping deceleration trough 118 is connected to the upper end of the ice-melting residue trough 119. The ice-melting residue trough 119 has no bottom and is open on the side. The open end is connected to the residue removal port 112 provided on the side wall of the melting refrigerator 102. 07 is connected; the ice melting residue tank 119 is equipped with multiple layers of removable ice melting residue nets 120, and the aperture of the ice melting residue nets 120 decreases from top to bottom; the periphery of the residue guide plate 123 is sealed and fixedly connected to the inner wall of the melting refrigerator 102 and forms a water storage space with the inner wall of the melting refrigerator 102 above the residue guide plate 123, and the water storage space is connected to the ice melting water supply port 115, the spray return water interface 116 and the waste water discharge valve 117 provided on the side wall of the melting refrigerator 102; a cleaning water supply interface 114 connected to the cleaning spray pipe 122 is also installed on the side wall of the melting refrigerator 102.

[0040] A side cover plate is movably connected to the slag removal port 107 , and a plurality of sealing bolts 110 are provided on the side wall of the thawing refrigerator 102 around the side cover plate.

[0041] The cleaning spray pipe 122 is arranged in a ring shape, and is provided with a plurality of nozzles facing the slag guide plate 123 .

[0042] A detachable top cover 103 is provided on the top of the melting refrigerator 102, and the top cover 103 is connected to the melting refrigerator 102 via a plurality of fasteners 104; an ice insertion port 105 and a cleaning and maintenance port 106 are provided on the top cover 103 of the melting refrigerator, and both the ice insertion port 105 and the cleaning and maintenance port 106 are provided with an openable and closable cover plate, both of which are connected to the top cover 103 of the melting refrigerator via a hinge 108, and a handle 109 is fixed to the cover plate; the ice insertion port 105 is located above the higher end of the ice insertion deceleration trough 18.

[0043] Multiple branch pipes are vertically mounted on the top cover 103 of the thawing refrigerator. Each branch pipe is equipped with a water diverter valve 112. The upper ends of each branch pipe are connected to a spray water supply pipe 111, and the end of the spray water supply pipe 111 is also equipped with a spray water supply quick connector 113. The lower ends of all branch pipes pass through the top cover 103 and extend into the thawing refrigerator 102. A spray pipe is horizontally mounted at the lower end of each branch pipe. Each spray pipe is equipped with multiple downward-facing high-pressure sprayers 124. Some of these high-pressure sprayers 124 are located above the ice drop deceleration tank 118, while others are located above the ice melting residue trough 119.

[0044] The ice-dropping deceleration trough 118 and the slag guide plate 123 have the same inclination direction, with a slope of 5% to 10%; the ice-melting water supply port 115 is located above the wastewater discharge valve 117, and the wastewater discharge valve 117 and the lowest end of the slag guide plate 123 are at the same horizontal plane, which can ensure that impurities deposited on the slag guide plate 123 can be discharged smoothly.

[0045] The skid-mounted base 1 adopts a hollow structure to facilitate forklift mounting or manual skid mounting.

[0046] The working process of the spray type rapid ice melting water supply device is as follows:

[0047] Before use, close the side cover on the slag removal port 107, tighten the multiple sealing bolts 110, and press the side cover against the side wall of the thawing refrigerator 102 through the multiple sealing bolts 110 to prevent water leakage.

[0048] Connect the spray water supply quick connector 113 to the hot water end of the hot water boiler 2, open the valve on the spray water supply quick connector 113, and the high-pressure and high-temperature spray hot water generated by the external spray water supply system enters the high-pressure sprayer 124 through the spray water supply pipe 111 and the branch pipe in turn and is sprayed into the melting refrigerator 102. At the same time, open the upper cover of the ice injection port 105, and throw ice cubes and snow cubes into the ice injection deceleration groove 118. In the process of sliding downward along the ice injection deceleration groove 118 and entering the ice melting filter trough 119, the ice cubes and snow cubes come into contact with the high-temperature and high-pressure hot water sprayed by the high-pressure sprayer 124 and melt into water. In the process of flowing downward into the bottom of the melting refrigerator 102, the melted water contacts the multi-layer ice melt arranged in the ice melting filter trough 119. The filter residue net 120 performs contact filtration, filtering out insoluble impurities of different particle sizes in the melt water step by step. The filtered melt water falls downward into the water storage space. After settling for a period of time, the water quality is tested. If the water quality meets the standard, most of the melt water enters the melt water straight discharge pipe 5 through the ice melt water supply port 115 for discharge, and a small amount of melt water enters the cold water end of the hot water boiler 2 through the spray return water interface 16 as a spray water source; if the water quality does not meet the standard, most of the melt water is discharged through the ice melt water supply port 115 into the joint water purifier 3 for further purification, and a small amount of melt water continues to enter the cold water end of the hot water boiler 2 through the spray return water interface 116 as spray water (Note: the hot water boiler 2 does not have high requirements for water quality, and its internal boiling and evaporation can also improve the spray water quality).

[0049] After long-term use, silt and other impurities will accumulate on the surface of the slag guide plate 123, and then the machine needs to be shut down for maintenance. Close the ice injection port 105, disconnect the external spray water supply system, and discharge all the melt water in the water storage space through the ice melting water supply port 115. Open the cleaning water supply interface 114, and spray the external cleaning water source evenly on the slag guide plate 123 through the spray hole on the cleaning spray pipe 122, and then open the wastewater discharge valve 117 to release the muddy water wrapped in the slag, until the slag guide plate 123 is clean, close the cleaning water supply interface 114 and stop cleaning; during the cleaning process, open the top cover of the cleaning maintenance port 106 to observe the internal situation of the melting refrigerator 102. Once large particles of impurities are found blocking the wastewater outlet, immediately cut off the water supply and clear them.

[0050] During this operation, hot water for ice melting is provided by the hot water boiler 2. The high-pressure sprayer 124 utilizes a conventional multi-hole nozzle to spray high-pressure, high-temperature hot water. The ice drop reduction chute 118 is a chute with a number of ridge-shaped speed reduction strips evenly distributed on its bottom surface. These speed reduction strips are used to slow down the movement of ice and snow, extending its travel time and ensuring its full melting. Furthermore, the tilted design of the ice drop reduction chute 118 prevents ice from clogging the ice drop opening 105.

[0051] Five layers of ice-melting filter residue nets 120 are arranged from top to bottom in the ice-melting filter residue trough 119. The mesh sizes of the five layers of ice-melting filter residue nets 120 are 5mm, 2mm, 1mm, 0.5mm and 0.1mm, respectively, from top to bottom. They can filter insoluble impurities of different particle sizes mixed in ice and snow blocks. The ice-melting filter residue nets 120 can be made of environmentally friendly PP material. Each layer of ice-melting filter residue nets is made of a hard frame and a filter screen installed in the hard frame, which is easy to take and put. A slag removal handle 121 is fixed to the hard frame. When slag removal is required, loosen the sealing bolt 110, open the side cover on the slag removal port 107, and remove the ice-melting filter residue net 120 from the ice-melting filter residue trough 119 by pulling the slag removal handle 121 to remove the filter residue trapped on the ice-melting filter residue net 120.

[0052] The slag guide plate 123 can be made of a smooth plastic plate, and the distance between its lower end and the ice-melting water supply port 115 is not less than 10 cm, which can better precipitate impurities and ensure that clean water flows out of the ice-melting water supply port 115.

[0053] 2. Vacuum multi-stage cascade water purification device

[0054] like Figure 5-7 As shown, the vacuum multi-stage cascade water purification device 3 includes a second skid-mounted base 301, and the second skid-mounted base 301 is installed with a primary cascade water purifier 302, a secondary cascade water purifier 303, a buffer and thermal insulation water tank 304 and a first integrated control box 306; the water inlet end of the primary cascade water purifier 302 is connected to a clean water supply pipe 315, the water outlet end of the primary cascade water purifier 302 is connected to the water inlet end of the secondary cascade water purifier 303, the water outlet end of the secondary cascade water purifier 303 is connected to a clean water outlet pipe 307, a clean water outlet pipe 307 is provided with a clean water outlet valve 1, and the end of the clean water outlet pipe 307 is connected to the buffer and thermal insulation water tank 304, and the bottom of the buffer and thermal insulation water tank 304 is connected to a water storage and supply valve 310; the first integrated control box 306 is respectively connected to the primary cascade water purifier 302 and the secondary cascade water purifier 303 for signals.

[0055] A vacuum drainage assembly 305 is installed on the skid-mounted base 1 next to the buffer insulation water tank 304. The vacuum drainage assembly 305 includes a first vacuum collecting tank 311, a first vacuum pump 312 and a first vacuum drainage water storage tank 313. The water inlet end of the first vacuum collecting tank 311 is connected to the first vacuum drainage pipe 314, and the first vacuum drainage pipe 314 is connected to the clean water outlet pipe 307; the water outlet end of the first vacuum collecting tank 311 is connected to the first vacuum drainage water storage tank 313, and a first vacuum drainage valve 316 is provided at the bottom of the first vacuum drainage water storage tank 313; an exhaust pipe is provided at the top of the first vacuum collecting tank 311, and the end of the exhaust pipe is connected to the first vacuum pump 312; the first vacuum pump 312 and the first vacuum collecting tank 311 are respectively connected to the first integrated control box 306 for signals.

[0056] The working process of the vacuum multi-stage cascade water purification device is as follows: connect the ice melt water supply port 115 to the clean water supply pipe 315, open the clean water supply valve 308 to inject the melted ice and snow water into the primary cascade water purifier 302, start the primary cascade water purifier 302 and the secondary cascade water purifier 303 through the first integrated control box 306, and the melted ice and snow water is preliminarily purified by the primary cascade water purifier 302 and then flows into the secondary cascade water purifier 303 for secondary purification (in actual application, a booster pump can be added between the primary cascade water purifier 302 and the secondary cascade water purifier 303 to supplement the pressure drop); then open the clean water outlet valve 309 and close the vacuum water inlet valve 317 in front of the first vacuum collecting tank 311. The purified melted water flows into the buffer insulation water tank 304 through the clean water outlet pipe 307 for storage, and the water storage supply valve 310 is opened for external use when needed.

[0057] After the melt water is purified, the clean water supply valve 308 and the clean water outlet valve 309 are closed and the vacuum inlet valve 317 in front of the first vacuum collection tank 311 is opened to ensure that the residual water after the first vacuum pump 312 is started to evacuate the vacuum can enter the first vacuum collection tank 311 along the first vacuum drainage pipe 314; the first vacuum collection tank 311 is used to ensure vacuum and collect residual water. Generally, the lower 1 / 3 of the volume in the tank is used to collect residual water, and the remaining 2 / 3 of the volume in the upper part is used to ensure vacuum; the negative pressure in the first vacuum collection tank 311 is generally set at -55~-65kPa. When the upper limit of the pressure in the first vacuum collection tank 311 is reached, the first vacuum collection tank 311 is opened. The pump 312 automatically stops; when the pressure drops to the lower limit within the first vacuum collection tank 311, the first vacuum pump 312 automatically starts. A check valve (not shown) is installed between the first vacuum pump 312 and the first vacuum collection tank 311 to prevent gas from flowing back when the first vacuum pump 312 stops. When the water level in the first vacuum collection tank 311 reaches a set height, a pump (not shown) installed between the first vacuum collection tank 311 and the first vacuum drainage water storage tank 313 automatically starts, pumping the water from the first vacuum collection tank 311 into the first vacuum drainage water storage tank 313 for storage. A check valve is also installed at the outlet of the first vacuum collection tank 311 to prevent backflow of water from the first vacuum drainage water storage tank 313. A safety valve is also installed at the top of the first vacuum collection tank 311 to prevent excessive negative pressure within the tank when the vacuum pump is operating. The water in the first vacuum drainage water storage tank 313 is essentially purified water. Although it cannot be drunk directly, it can be used for daily washing. When needed, the first vacuum drainage valve 316 can be opened to drain it for use.

[0058] Before using the vacuum drainage component, a sealing test is performed. That is, when the clean water supply valve 308 and the clean water outlet valve 309 are closed, the first vacuum pump 312 is started to make the negative pressure in the first vacuum collection tank 311 reach -65kPa, and then the first vacuum pump 312 is turned off. The negative pressure does not decrease by more than 10% after one hour.

[0059] During the above-mentioned operation, both the primary and secondary water purifiers 302 and 303 utilize the Zhongjin Huilong SNSJ03-400 outdoor water purification device. The buffer and insulated water tank 304 serves as a water storage device for the vacuum multi-stage water purifier after the water purification process is activated. The buffer and insulated water tank 304 is made of double-layer stainless steel, with the stainless steel interlayer filled with foam and other insulation materials to prevent the purified water inside the buffer and insulated water tank 304 from freezing. The first integrated control box 306 is a standard PLC control cabinet with built-in PLC control elements. It controls the coordinated operation of the primary and secondary water purifiers 302, 303, the first vacuum collection tank 311, and the first vacuum pump 312 through a combination of manual and automatic control. For all other undescribed areas, equivalents in the prior art that achieve the same functions or effects are used.

A desalination capacitor adsorber 404 is installed on the clamp 408. The water inlet end of the desalination capacitor adsorber 404 is connected to a water supply pipe 410, and the water supply pipe 410 is also provided with a water supply control valve 41. 1, and the end of the water supply pipe 410 is connected to the water outlet of the water supply pump 405 installed on the third skid-mounted base 401, the water inlet end of the water supply pump 405 is connected to the water inlet pipe, and the water inlet pipe is provided with a water supply inlet valve 409; the water outlet end of the desalination capacitor adsorber 404 is connected to the water outlet pipe 415, and the end of the water outlet pipe 415 is provided with a water outlet quick connector 418, the desalination capacitor adsorber 404 and the water supply pump 405 are respectively connected to the second integrated control box 403 for signal connection.

[0062] A water outlet control valve 414 is installed on the water outlet pipe 415, and a second vacuum drainage pipe 413 is connected to the water outlet pipe 415 between the water outlet control valve 414 and the desalination capacitor adsorber 404. The other end of the second vacuum drainage pipe 413 is connected to the water inlet end of the second vacuum collecting tank 412 arranged on the third skid-mounted base 401, and the water outlet end of the second vacuum collecting tank 412 is connected to the second vacuum drainage water storage tank 416, and a second vacuum drainage valve 417 is provided at the bottom of the second vacuum drainage water storage tank 416; an exhaust pipe is also provided on the top of the second vacuum collecting tank 412, and the end of the exhaust pipe is connected to the second vacuum pump 406, and the second vacuum pump 406 and the second vacuum collecting tank 412 are respectively connected to the second integrated control box 403 signal.

[0063] The second integrated control box 403 is an integrated controller (common PLC control box) for the vacuum drainage antifreeze device for brackish water purification. It controls the coordinated operation of components such as the desalination capacitor adsorber 404, the water supply pump 405, and the second vacuum pump 406 through a combination of manual and automatic control.

[0064] The equipment protection cover 419 is installed on the outside of the water purification skeleton 2, and plays the role of protecting the desalination capacitor adsorber 404, the water supply pump 405, the second vacuum pump 406, the second vacuum collection tank 412, the second vacuum drainage water storage tank 416 and other components and their pipelines and control valves.

[0065] The working process of the desalination water purification device 4 is as follows:

[0066] The water inlet pipe of the water supply pump 405 of the desalination water purification device is connected to the buffer insulation water tank 304 of the vacuum multi-stage cascade water purification device 3. The water supply inlet valve 409 and water supply control valve 411 are opened, and the water supply pump 405 is started to pump melt water into the desalination capacitor adsorber 404 through the water supply pipe 410. The desalination capacitor adsorber 404 is started to perform electrical desalination on the melt water. Then, the water outlet control valve 414 is opened to send the desalinated and purified melt water to the outside through the water outlet pipe 415. The end of the water outlet pipe 415 is equipped with a water outlet quick connector 418 to facilitate connection with the external water supply pipeline. Note that during this process, the second vacuum pump 406 is not operating, and no water enters the second vacuum collection tank 412. The desalination capacitor adsorber 4 adopts the existing CDI capacitor desalination device or MCDI membrane capacitor desalination device, specifically the IS-2H membrane capacitor desalination device produced by Beijing Qingshui Lantian Technology Co., Ltd.

[0067] After desalination and water purification, the desalination and water purification device can be vacuum-drained using the second vacuum pump 406, the second vacuum collection tank 412, and the second vacuum drainage water storage tank 416. The specific process is as follows: close the water supply inlet valve 409 and the water outlet control valve 414, and open the water inlet valve of the second vacuum collection tank 412 to ensure that residual water after the second vacuum pump 406 is started to evacuate the water can enter the second vacuum collection tank 412 along the second vacuum drainage pipe 413; the second vacuum collection tank 412 is used to ensure vacuum and collect residual water. The negative pressure in the tank is generally set at -55~65kPa. When the negative pressure is lower than the lower limit, the second vacuum pump 6 automatically starts. When the negative pressure reaches the set upper limit, the second vacuum pump 6 automatically stops running; this reciprocating process ensures that the vacuum degree in the second vacuum collection tank 412 is constant to meet usage requirements. A check valve (not shown) is installed between the second vacuum pump 406 and the second vacuum collection tank 412 to prevent backflow of gas when the second vacuum pump 406 stops operating. When the water level in the second vacuum collection tank 412 reaches a set height, a pump (not shown) installed between the second vacuum collection tank 412 and the second vacuum drainage water storage tank 416 begins to operate, pumping the water into the second vacuum drainage water storage tank 416 for centralized storage. A check valve is also installed at the water outlet of the second vacuum collection tank 412 to prevent backflow of water in the second vacuum drainage water storage tank 416. A safety valve is also installed at the top of the second vacuum collection tank 412 to prevent excessive negative pressure in the tank when the vacuum pump is operating.

[0068] Before using the vacuum drainage component, a sealing test is performed. That is, when the water supply inlet valve 409 and the water outlet control valve 414 are closed, the second vacuum pump 406 is started to make the negative pressure in the second vacuum collection tank 412 reach -65kPa, and then the second vacuum pump 406 is turned off. The negative pressure does not decrease by more than 10% after one hour.

[0069] Taking into account the low temperature in high altitude and cold areas, the ice melting water supply and water purification integrated station of the present invention should be set up in a simple station building, equipped with auxiliary heating equipment such as heaters and coal stoves to insulate the vacuum multi-stage cascade water purification device and desalination water purification device.
